电力变压器、反应器、供电机组及其组合的安全性.第2-9部分:Ⅲ类手用钨丝灯变压器和供电机组的详细要求和试验

[中文适用范围]： IEC 61558的这一部分涉及用于钨丝灯的III类手提灯的变压器和包含用于钨丝灯的III类手提灯的变压器的电源装置的安全性。该标准还涵盖了包含电子电路的变压器。 [外文原描述]： IEC 61558-2-9:2010 deals with the safety of transformers for class III handlamps for tungsten filament lamps and power supply units incorporating transformers for class III handlamps for tungsten filament lamps. Transformers incorporating electronic circuits are also covered by this standard. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. The main changes consist of updating this part in accordance with IEC 61558-1:2005, and adding power supply units to the scope. This part has the status of a group safety publication in accordance with IEC Guide 104. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. In the meantime, the previous edition can still be ordered by contacting your local IEC member National Committee or the IEC Central Office. This publication is to be read in conjunction with IEC 61558-1:2005 .
